TPK600/900 CHASSIS MOUNTED NON-INDUCTIVE POWER FILM RESISTOR TO227

Download PDF File

INTRODUCTION
These are compact TO227, 600W high power resistors.  attachment to an air cooled or water cooled heatsink
is necessary.  Rated power is 600W (single and dual elements).  These units come with M4 screw terminals.
They Exhibit very low series inductance, high density installation, vibration proof and the possibility of
perfect heat dissipation.  Applications include:  Snubber resistors for power supplies, gate resistors, pulse
generators, high frequency amplifiers, dumping resistors for theater audio equipment (i.e. Dividing networks
for loud speaker systems)
